METAL BUILDING STRUCTURE Filed May 28, 1951 f////lA INVENTOR /2/7/5 a(/We ATTORNEYS Patented Apr. 5, 1932 UNITED`v STATES PATENT OFFICE MILLSG. CLARK, Olli' CLEVELAND HEIGHTS, OHIO, ASSIGNOR TO THE DTSULATED STEELFLOOR & WALLCOMPANY, F CLEVELAND, OHIO, A CORPORATION 0F OHIO :METALBUILDING STRUCTURE Application led Hay 28, 1931. Serial No. 540,647.

This invention relates to wall units for building construction, andcontemplates such a unit which shall be of sufficient strength andrigidity and have proper Weather-proofing and heat and sound insulatingproperties to serve in itself without a supporting frame-work, as acomplete Wall panel; so that 'a building may be constructed of wallscomprising solely a plurality of such units, to le which, on the inside,may be directly applied a linish coat as a plaster or the like, and onthe outside weatherproolng and decorative material. v

'ihe principal obj ect of this invention then te is to provide abuilding wall unit of the class described and more particularly onecomprising a sheet metal bent to form adjacent channels opening onopposite sides, and nonmetallic members lling said channels and E2@secured therein, whereby said wall unit has a non-metallic body, with ametallic reinforcing having portions at the opposite faces of the unitand portions extending therebetween.

' Another object is to employ for the purpose of securing togethermembers of the unit, a material which is both adhesive and protective;and to apply this material to all sizes of all members before theirassembly into the unit, whereby in the assembled unit all exposed sidesare protected by a single thickness of protective coating, and allabutting sides of adjacent members are secured by double thicknesses otadhesive coating therebetween.

A further object of the invention is to so arrange the metal member ofthe unit that a plurality of the units each comprising a wall panel, maybey rigidly and permanently secured together as by welding, to provide asubstantially continuous complete wall.

Another obj ect is to make the metal portion of the wall of such formthat units may be joined with equal facility either end to end or inangular relation as at corners.

And still another object is to provide novel means for joining unitswhere the desired buildingdimensions are not such as to be provided by amere plurality of complete units.

The exact nature of this invention together with further objects andadvantages thereof will be apparent from the following description takenin connection with the accompanylng drawings, in which Fig. l is a topend view in perspective illustrative of a unit embodying the invention;Fig. 2 is a plan vview illustrative of the manner of joining togethersuch units in building construction; Fig. 3 is a view similar to that ofFig. 1 showing a completed wall section to which the finish materialshave been applied; and Fig. 4 is an enlarged view of a typical sectionFig. 3.

With reference now to the drawings and particularly to Fig. l thereof,the principal parts ofthe unit shown are a sheet metal member 1and threenon-metallic members 2. The member -1 is bent preferably rectangularlyas indicated, to form adjacent channels openlng on opposite sides of thegeneral plane of the unit. ln the unit illustrated Fig. l there areprovided three channels of rectangular section, a central one openingfrom the observer, and on either side thereof a channel opening in theopposite direction or toward the observer. rlhe locations of the bendsare such that these channels are ofequal width and depth, so that theouter edges of the metal member ,dene a rectangular solid of thicknessequal to approximately that of the depth of the channels, of widthapprom'mately three times the width of one of the channels, and ofrelatively greater length. The dimensions of this gure may thus be 2thickness, 18 width and 10 in length.

For each of the channels l provide a nonmetallic iller which'may be ofany of the numerous so-called wall-bored materials,hav ing relativelylight fibrous or cellular structure and usually representing aby-product of an industry. Such by-products of the lumber, sugar,turpentine, peanut, cork, asbestos, and other industries, are to be'found on the market. These filler members are each of sectionaldimension to iit into one of the channels and preferably of lengthcorresponding to that of the metal member, so that when the assembly ismade as in Fig. 1, a rectangular solid will be formed having outsidedithe assembly be weatherproof, with all of the 1 members protectedagainst moisture, and that the filler members may be firmly secured inthe assembly, I employ in the following manner a coating material whichhas adhesive and protective properties such as emulsiiied asphalt.

Before assembly of the parts all are dipped in such material so as toreceive a coating thereof, so that each of the four members has its owncoating on all of its sides. The filler members 2 are then pressed intothe metallic plan view Fig. 2.

member 1. It will be apparent that in the assembled unit, all exposedsides are protected by a single thickness of preservative coating, andall abutting sides of adjacent members are secured together by doublethicknesses of adhesive coating therebetween. The double thickness ofthe coating is indicated Fig. l as at 3 whereinthe coating acts as abinder, andby a thinner line as at 4 wherein the coating acts merelyV asa preservative or protection for the outer wallv of the assembled unit.

It willbe noticed that in the assembled unit the bulk of the unit iscomposed of the relatively light material of the fillers 2 but themetallic member 1 acts as a reinforcing so that the unit has therigidity and strength of structural metal.

It will also be observed that, neglecting the coating material, thereinforcing has portions as at la in the opposite faces of the unit andtransverse portions as at 1b extending directly therebetween. Also metalportions 1c are disposed at the side faces of the unit.

The units are obviously adapted to be ernployed in a wall structure,with their members running vertically, as indicated in the Since metal1c is disposed at the end edges of each unit, a pair of units, arrangededge to edge be secured as by welding up and down the seams thus made,as at a.' The coating material may be scraped or burned off to permitthe welding. A wall corner may be formed bydisposing adjacent units asat B, Fig. 2, and welding as at b. A partition wall may be had bydisposing the parts as at C and welding as at c. It will be appreciatedthat in any or all of these cases the metal reinforcing members of theseveral units are made in effect continuous so that a rigid wallstructure of great strength is had.

It is usually desirable that a nishbe ap- A plied to the walls. .Thus asindicated Fig. 3,

on the outside a thin coat 5 of stucco or the like may be applied asthrough compressed air guns directly to the outer faces of the assembledunits; -or indeed clapboards may be applied as it will be obvious thatnails can be nicely driven into the liller members 2 beas at A, Fig. 2,may.

-`verse portions extending directly Lasaooa tween the facing reinforcingmetal portions On the inside the finish will largely depend upon. thedecorative eect desired. In some instances it lap or other coarsetextile material be applied to the inner wall face, to overlie theportions 1a of the metallic reinforcing in this face, and thenon-metallic face portions therebetween. The sheet 6 may be secured byan additional thin coat of emulsified asphalt or the like. In many casessuch a covering as a suitable textile 6 may suliice for finish. In otherinstances it may be desired to overlay upon the covering 6 a thin finishcoat 7 of plasterl or the like.v Q

Fig. 4 thus illustrates a complete exterior wall section as at the jointA, Fig. 2, wherein the reference characters correspond with those in theother figures so that the parts are already identified. It may be herenoted, however, that outside of the finish material the wall has atevery section therethrough, a principal thickness of the material of themembers 2 which is of excellent soundproof qualities and highlyresistant to heat transfer. lThe section also includes a thickness ofthe metal reinforcing member l. Overlaid upon either side is a finishmaterial concealing and protecting thejointbetweenunits.
